Are you actually calling me a liar about my real life example? If yes, you owe me an apology or a mod owes you a visit to BanTown for insultiing behavior.
It really did happen. The GM was Ned, and the other players were Paul and Nicole.
Ned gave a simple description of "it's like the Ewok Village" We climbed up the ladder, got attacked from another platform, and Paul announced his act of idiocy.
Paul tends to acts of idiocy, and our group has 2 choices, let him die (and possibly take us with him) and have to keep spinning up new PCs into the party, or pause the game, talk him off the ledge and resume. We choose the latter.
Paul is a good friend, a good portrayer of character and a good team player. He's not always so good with acts of spontaneity. He also gets silly when he doesn't take things seriously. So letting him plow through PCs means he will stop taking the game seriously because he doesn't take his PC seriously anymore.
A situation like this can happen in the blink of an eye. I was surprised when he said "I run and jump across to the other platform!" There are some GMs who I have met who would have rolled the Jump check and said "OK, you run and jump and fail to cross the 20' and fall 60' to your death."
[MENTION=26473]The Shaman[/MENTION] implies with his other statements that he normally lays out minis, diagrams, etc. If he was GMing and the situation played out like I describe (no chance to draw or explain before Paul blurts out, would he make Paul jump and die?
So the player, without requesting clarification on distance, decided to try to close distance in ranged combat in an Ewok Village style setup where there is no bridge between the platforms that he's dealing with...
When the Ewok village as presented throughout the movie which I have never seen looks like this?

I know what an Ewok village looks like. I've played in many Halfling, Elven, Rogue, etc. cities in the trees that look like it. It is a trope. The player requested no clarifying information, no confirmation on the layout, distances, but assumed that they would just mystically close distance through their jump?

Look into the eyes of these adventurers. So abused, neglected, and unloved. They are starving in dungeons because no one brought food, broken limbs due to badly-placed jumps, and other terrible ailments. For only the price of a few Cure Moderate Wounds you too could help us give these adventurers a new home...
